I can not activate a new install of Windows Server 2003 x64. Install was successful and networking is fine. Each time I receive an error that activation can not be completed at this time. I used a valid (so I thought) key. I have others but if I recall correctly, if an invalid license is used, it says so. Any suggestions?WpC
